[Crosstoolchain-logs] [device-tree-compiler] 133/198: Add a basic test for fdtdump

[Hector Oron]

This is an automated email from the git hooks/post-receive script.

zumbi pushed a commit to branch upstream/1.4.x
in repository device-tree-compiler.

commit 76a65b14d1bb10f300f518c11aed231575521c2e
Author: Simon Glass <sjg at chromium.org>
Date:   Wed Jun 18 21:24:32 2014 +1000

    Add a basic test for fdtdump
    
    We can test fdtdump by comparing its output with the source file that was
    compiled by dtc. Add a simple test that should at least catch regressions
    in basic functionality.
